Handcrafted from premium pigmented concrete and reinforced with internal steel, the Cubrosa planter is engineered for real-world durability. Its raw finish boasts gentle pitting and tactile character, while the deep Onyx Dusk pigment — a rich blend of charcoal, black, and grey — ensures the color remains consistent and resists fading or peeling.

Suitable for both private gardens and commercial spaces, the planter's 33.5kg weight offers natural security against movement and theft. It stands strong against frost, UV damage, and moisture, making it a reliable feature in every season.
